CONCENTRATING APPARATUS.

To (LZZ whom t may concern.'

ie it known that I, JULiUs MATTER, of Laaken, near the city of Barmen,Germany, have invented certain new and useful Improvements inConcentrating Apparatus, of which the following is a specification,reference being had therein to the accompanying drawings, forming partof this specification.

Figure l is a vertical section of one form of my apparatus, Fig. 2is avertical section of the evaporating pan on an enlarged scale, Fig. 3 isa top view of Fig. 2. Fig. Ll is a detailed sectional view. f

The object of this invention is to produce an organized apparatus forthe concentration or evaporation of lye and other liquids to any desireddegree.

I herein describe the apparatus in connection with the concentration oflye used in textile manufacture.

The apparatus comprises a casing a of wood or metal. In said casing aresecured on opposite walls b, 7) the supports c c and (l d in differentheight and on said supports are placed the pans e, e, each assuming aninclined position, as shown and in such a manner that the upper pan einclines from left to right and the lower pan e from right to left andso on.

The particular construction of the pan may be understood from Figs. 2and 3. Each pan has the upright walls f, forming a receptacle ofrect-angular shape as shown in Fig. 2 and being open at the top. g isthe bottom of the pan., which has the compartments h, k', thatcommunicate With each other by apertures m and are closed by lids m. Thecompartments are adapted to receive hot air, steam and the like to heatthe inner bottom surface n of the pan. Said surface is fitted with ribs0 and these ribs are arranged as shown in Fig. 3 leaving alternatelyopenings 0l at the walls f and 02 in their middle portion, so that aliquid may flow over the surface n from one end to the other end in thedirection of the arrows. Between the said ribs in the pan are securedvertical walls 79 made of sheet metal or the like which leave an openingor passage n over the surface n. The pan e is fitted with a pipe g,carryinga funnel g', a pipe s eX- Speccaton of Letters Patent.

tendinglfrom the other end of the pan and discharging into a funnel s ofa pipe t which branches from the rear of the pan e. t is a dischargingpipe.

In operation, lye is illed or pumped into the apparatus at g', iowingslowly in a thin sheet or iihn over the surface n through 'the upper pane and then through the pipe connection s, t into the lower e and so onif there are more than Itwo pans. Into the bottom compartments lr, it ofeach pan is fed lsteam or hot air which thoroughly heats the bottomsurface n and their ribs and by the heat thus produced the lye will bereadily evaporated and a high degree of concentration may be obtained.The foam which is absorbed from the lye is permitted to pass into thecompartments u formed by the vertical walls 7) and in this way anunhindered concentration can take place. The vapors gathering in theroof v may escape through the chimney fw.

Having thus described the nature of my invention what I desire to secureby Letters Patent is:

1.y An apparatus of the class described comprising in combination, aplurality of evaporating paus arranged for one to deliver to the otherand provided with means for causing the liquid to flow in a eircuitousor tortuous path, independent means for heating each pan, and aplurality of partitions arranged slightly above said first mentionedmeans and transversely with respect to the flow of the liquid.

2. An apparatus of the class described comprising im combination, anevaporating housing provided with an outlet, an evaporating pan disposedin said housing and in an inclined position and provided with means forcausing the liquid to How thereover in af circuitous or tortuous path,means for heating the pan, and a plurality of partitions arrangedslightly above and between said rst mentioned means and* forming aplurality ofcompartments in the pan for permitting the vapor to risetherefrom.
